Improvement in corn-droppers



Cduitt %tatet JACOB II. GROSS, OF NIAN'IIC, ILLINOIS.

Letters Patent No. 111,200, dated January 24, 1871.

IMPROVEMENT IN CORN-DROPPERS.

The Schedule referred to in these Letters Patent and making part of thesama.

enable others skilled in the art to make and usey the same, referencebeing had to the accompanying drawing forming part of thisspecification.,

M y invention relates to machines for sim ultaneonsl y dropping corn andchecking off the rows.

I will first describe my invention in connection with all that isnecessary to a full understanding thereof', and then clearly point itont in the claim.

Figure l is a sectional elevation taken on thc-line :vx of g. 2; and

Figure 2 is a top View of my improvechmachine.

f Similarletters of reference indicate corresponding parts.

A represents a p air of runners, of any suitable kind; and

B, a transverse shaft, mounted thereon, near the front, by clamping thejournal boxes C to vertical bars D, which have elongated holes E for theclamping-bolts F, so that the shaft may be adjusted higher or loweron"the said bars. Y

G represents the star-wheels; .they are mounted on the shaft outside therunners, so that the points will engage with the ground, as 4the runnersmove along,

to cause them to he revolved; they should he of suchv size as to maketwo movements of the dropping slide to one revolution, but they may belarge enough to make three or four.

His a gear-wheel, placed on shaft B, to turn the shaft I, having awheel, K, gearing with it, and working lthe dropping-slide L andthecheck-shaft INI. `It moves the dropping-slide L by means of the tappet Nacting on the studs O, imparting two movements to it at each revolution.

. This slide has two pockets at each end, inside of the hoppers I?,which drop alternately, being suitably arranged relatively to the holesin the bottom of the hoppers, which are arranged over the Scrapers Q, attached to the rear ends of the runners, for scraping out a channel forthe corn to fall into.

The cheek-shaft Mis provided with two arms It,

at each end, which strike the ground at each revolution of the saidshaft and make checking Vmarks thereon. These arms are so arranged onthe shaft, and the latter is so geared relatively to thedrop-slide,

that the marks will be made exactly by thesidcs ofthe places where thecorn is dropped, thereby checking the rows perpendicular to themovements ofthe machine so that the rows may be made regular each Way.

Ihe driving-wheel H is made to slide on the shaft B, and provided with ashifting lever, T, extending rearward, so that the attendant walkingbehind may shift it out and in, as required, at the ends ofthe rows, tostop the'action of the dropper and marker when turning, and to set themin: gear again after turning.

The bar at the rear, which supports the rear end of shaft I, alsosupports the bars V, which project rearward and support the shaft M, andthese bars are supported at the front on the shaft B; and the said bar Vis supported on the hoppers which are connected together by the troughXV, which is designed to be attached to the runners so as to be readilydetached, so that the whole operating apparatus may he readily appliedto or removedfrom the runners, theY plates D being also detaehahlyconnected.

Having thus described my invention,

I claim/as new and desire to secure by Letters Pat; cnt- Thejournal-boxes C C, vertical slotted bars E, and bolts F, combined asvdescribed with shaft B, for the -'purpose ofadjusting the star-wheelsat a greater or vlesser height.
